I´m a new user of VarAC and already the VarAC virus is set :-)
I had already chats with some users and and it works really great. I like it so much because it is not FT8, just SNR Exchange and is very fast with the registered Version of VARA HF modem.

73 de Andre ... and looking forward to get the one or other on the air :-)
